   A switch receives a frame with an FCS error. What does the switch do with this frame?

   • AIt drops the frame and increments an error counter.
   • BIt floods the frame to all ports to ensure delivery.
   • CIt sends the frame to the CPU for further processing.
   • DIt forwards the frame to the destination if the destination MAC is known.

   In an Ethernet frame, what is the purpose of the EtherType/Length field?

   • AIt contains the error-checking code used to detect corruption in the frame.
   • BIt synchronizes the receiving device to the incoming bit stream.
   • CIt indicates the type of protocol carried in the payload (e.g., IPv4 or IPv6) or the length of the payload.
   • DIt specifies the source and destination MAC addresses of the frame.

   What does a host do when it receives an Ethernet frame with a destination MAC address that does not match its own MAC address and is not a broadcast or multicast address?

   • AIt silently discards the frame.
   • BIt updates its MAC address table with the source MAC address.
   • CIt forwards the frame to the next hop.
   • DIt sends an error message back to the sender.

   A switch receives a frame with a destination MAC address that is not in its MAC address table. How does the switch process this frame?

   • AIt sends the frame to the default gateway.
   • BIt broadcasts the frame to all ports including the ingress port.
   • CIt floods the frame out all ports except the ingress port.
   • DIt drops the frame because the destination is unknown.
